Hello,
This two patches add support for GEM CMA objects import and export as dma-buf
file handles.
There's not much to be added about the patches themselves, they're pretty
self-explicit. The code is based on the Exynos DRM DMA-BUF implementation.
The exporter role has been successfully tested with the Renesas R-Car DU
driver.
